Man, another great looking build!.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

I have 2 Sendero boxes and 2 Trailwalker boxes, but am building my own garage. I just have way too many projects going at once (I struggle to stay focused on one task) so it's been fairly slow going. Almost there though...

(Sorry for the brief thread hijack)

Yeah, an 85mm shock would be a great option to have. I guess until then, I'll just have to add spacers on the shock shafts.

Same here on the wood bed. I've had ideas and seen some really nice wood beds on FB, but have yet to make one. I think I may try to make one on my next build this winter.

A bed made out of scale diamond plate would look killer with the PW body and the paint you chose."thumbsup"

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Topher, I can't do diamond plate, but I could probably make you an aluminum bed fairly easy. This is a trailer I'm in the process of building, but im sure the design could be adapted for a flatbed pretty easy...

My first post here goes to you, what an awesome looking rig!
Also have a Sherpa kit on the way, and your build made me want to go portal in the rear... :D

I see you have used SSD axle housing in other builds also, do you buy them finish built or piece them together yourself?
What are your opinion on Diamod Pro vs Pro44? Other than scale looks.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Thanks Stimpy!

Nice start to a garage there! I like the scale of it. If you were closer to me I’d be trying to coax those trailwalker boxes out of you :ror:

I saw one person use what I think was a wood grain duct tape and it was surprisingly good looking. And thanks! I think aluminum diamond plate would fit well with the overall look too.

I like that perforated look! I may have to hit you up about that before the next comp season. I’ll need fenders and a bed that get within sorcca class 2 rules to compete with this one.

Hey thank you! I prefer the pro44 mostly for looks and the pumpkin seems a little smaller. I like that there are different diff covers available for it too. Some even add a tiny bit of weight and looks.

I went with the diamond here so I could make sure the reverse cut ring and pinion gears can go on either side to get the axle rotation the same as the rear portal axle. They were pieced together but I do use the ssd universals.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

So through my guessing I had thought I’d be around 30% overdrive. This was a rough estimate by taking the 1.91 portal reduction stock and just subtracting the amount of OD I was adding with each piece. So 30% from the t case, 10% from the ring and pinion, and another 30-35% from the portal gears (not sure the exact ratio of the tgh wild). *edit, the t case is actually 15% not 30%

Decided to record it with the rear tire turning 10 times and seeing how many times the front turned. I end up right around 11.5 turns in front and 10 in rear which seems to be about a 15% overdrive?

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Decided to trim the cab a little bit to take out some of the lean.

Also got some diff portal gears coming to reduce the amount of overdrive in the rear and give me more overdrive up front. Hoping to get around 25-30% with this next change.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

I think it looks good now with the cab sitting more level!"thumbsup"

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

I'm surprised where the OD has ended up - looking at reductions:

front output = 1.0
front ring/pinion = 30/8 = 3.75

rear output = 1.0 / 1.15 (t-case OD - division because you're speeding up the rear, thus reducing the amount of reduction)
rear ring/pinion = 27/8 = 3.375 (OD ring/pinion)
rear portal = 20/15 = 1.333 (Wild TGH OD gears)

I get:

front reduction = 3.75
rear reduction = (1/1.15) * 3.375 * 1.333 = 3.91

This gives ~4.2% OD (using either (r-f)/r or Harley's average (r-f)/((r+f)/2) )

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

^ like. And that’s exactly why I gave up on the math of calculating ratios and have gone to a more rudimentary empirical method of just counting turns.

Thanks for going through all the math, I never sat down to work it out, just started building. The mild portal overdrive gears showed up yesterday so I’ll have those in this week sometime and will run a similar video to see where it ends up.

But to play with your math, if you multiply to get 1.15 instead of dividing then you get 7.9%. As we see though, the actual rate multiplied and doesn’t divide by 2 and we end up right under 16%.

(5.175-3.75)/(5.175 + 3.75) = 1.425/8.925 = 15.9%

Thanks B! I like it better more level as well, should have done it from the get go really.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Yeah, I've never actually checked the maths vs. reality on OD, just used the numbers to show me roughly where I am and foolishly trusted them :ror:

I've also been considering something similar with both a gamechanger 4.2 and vs4-10 + VFD, so I happened to have a few spreadsheets with everything worked out

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

And interestingly, if I play with my maths, but with a standard 30/8 ring/pinion in the rear I get 14.8% OD..

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Got the Sherpa out early today for a proper shakedown at my favorite spot out here. The truck did great, handled everything I threw at it including a couple lines that other rigs struggle with. Video coming soon.

Very happy so far, I didn’t change any gearing yet because I wanted to see how it did with the initial set up and the observed 15% OD. I’ll change the portal gears this week which should get it between 25-30%.

Hey looks fantastic. Takes a sidehill really well. Nice build overall. All it needs now is a Fargo badge above the grill. 😎

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Thanks everyone! Very much appreciated. If you follow me on social media you’ll surely tell I’m a big fan of this truck.

On that note, here’s another clip from the video that I posted separately on the gram.

I had originally planned on changing shocks down the road but I have to say I’m quite pleased with these incision shocks. I know they’re not the most well regarded shock for whatever reason (maybe the bladder?) but they’re working out great on here. Using a 70w oil, rebuilt them since I got em used, didn’t bother with green slime (I never do tbh) and they’re very smooth and haven’t lost a drop of oil after putting the rig through its paces. I’m happy with how it’s worked out having a 80mm shock on the rear portal and 90mm up front. Still has good reach. The optional springs worked out well too. Hopefully they continue to hold oil.

New portal gears in, TGH mild instead of wild this time, got me right about where I was hoping to be.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

How do you like it compared to the other comp rigs you have?

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

I like it a lot, it’s an enjoyable drive and has been pretty capable so far. No regerts!

I’ve been happy with all 3 though, not sure if I have a clear favorite but this one has been great to drive.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Excellent build, I especially like the stance after you re-cut the body to flatten out the rake a bit. Looks aggressive enough, and has a bit more realistic feel to it.

Based on the videos, it certainly looks to perform quite well.

I'm starting on a g-speed v3 build and have a few questions, if you don't mind.

How do you like the sherpa vs the g-speed? I would expect them to be pretty similar, performance wise, but am curious how you find them.

Did you choose the ar45 for the rear for any specific reason(s)? I imagine it helps clearance over axle grabbing obstacles of course. Perhaps it helps with steep climbs keeping the rear 'up and out' a bit to improve the angle and thus cog during climbing?

I could be way off here, haha, just thinking through it a bit.

I'm planning on using ssd pro44 axles front and back, but after reading this thread, I'm starting to consider a rear ar45 option.

Cheers~

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

There wasn’t too much technical thought put into how it would work, other than figuring out how to gear it and expecting more clearance at the rear pumpkin. I just wanted to try it after seeing Brandon and Harley do this on the VS410 platform and see how it would do. Very happy.

If you read back a few posts you’ll see a lot of people ask that same question, as far as how it compares to the gspeed and other chassis options. The best answer I can give is they’re both solid products and you’ll be happy with either. My two rigs are set up too differently from each other for it to be a fair comparison of just the chassis itself, but I do know I’m satisfied with each one.

Hoping to do another Sherpa build down the road, and I already have a pair of gspeed rails on standby for the right opportunity.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

That makes sense. I just assembled my gspeed v3 today(what I have of it all), and found the fit and finish to be quite good. Excellent machining as well.

I may have to try the portal for the rear axle, being able to flip the transfer case to get the overdrive to the rear is very convenient to say the least.

Thank you for the insights, and for documenting another awesome build.

Cheers~

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Two questions,

What axles do you have in mind for the next Sherpa?

And do you think it would be worth buying rails only, and building around either an enduro base, or scx10.2? (Stock skids, trans, etc)

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

No problem, sounds like some fun is in your future. Happy building!

I’m thinking maybe portals for the next one, but that’s a long ways down the road and maybe not till next year so who knows what will be available then.

I do think the chassis alone is a worthy upgrade. The angled skid makes a significant difference in break over. Gspeed even has a kit that includes most of what’s needed for the enduro swap.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Working on a C2 legal body for the Sherpa. I slacked and missed the first comp of the season this past weekend but am planning on making it to a few this year.

Went with a Creep since it’s lean and mean, having a heck of a time deciding how to paint it but I think I’ve settled on something. Might get it done today. I’ve had some scale diamond plating around from Hot Racing for a while and decided to cut some for the bed. Couple mock up pics...

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

The creep body worked perfect for my last build, looking forward to seeing how you paint it! If you want to go a little further, I was able to mount a Capra interior in mine. Adds a little extra weight but turned out alright https://uploads.tapatalk-cdn.com/202...432db69fa1.jpg

Wrapped up the new body yesterday. I’ve been wanting to use this green/blue color for a while now and decided to bust it out. Went for a bit of a shop truck look and like the way the plating in the bed pops from main body color. The whole body is matted except for the windows of course and the Holmes hobbies logo on the hood. This was done in bright silver and has a flake type of finish so I left it shiny there.

Thanks for checking it out "thumbsup"

Looks good Fricker! I’ve been wondering what interior I could chop up and put in there so thank you for sharing that. I have an old bench seat type of interior laying around I may try and cut up and fit in soon.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

I love the new body, fantastic color, and excellent detail as usual. The diamond plate is a very nice touch as well.

Well done!

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Looks great TB!"thumbsup"

I'm digging that color! Gives it that old school look! Bed looks awesome with the plating!

It's cool your using the your logo on the door like your garage sign. I really like your sign! Great simple design that looks great and adds nice scale detail to your garage! I wish I had the imagination to come up with a cool looking sign for my garage! I'll have to get my brain in gear and see if I can come up with something! SRD LV did a great job on it!

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Thanks BMow! Glad you like it.

For the logo I just used a logo design app and made the best I could of the free options on there. Whipped this one up in a few minutes, may be worth giving them a look if you want some templates to work with "thumbsup"

Hey thanks!

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

That's cool! Logo looks great!"thumbsup"

I'll have to check out them apps and see what I can come up with!

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Nice looking rig and definitely a neat idea with the two different axles! Not sure if I missed it or not, but did you use wider hubs on the front to give it the same track width? I'm swapping AR44's and 3gear trans into my Capra and want to keep it the same width. Currently running VP Methods with a .225 hub. What hub do you think will get it back to that? I'm thinking a .725 would be close but I might be off base.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

I wanted to document this here, I'll drop a note in my thread as well. I shimmed mine, in the above manner, and used 0.4mm on top of the bearing. This took out very nearly all of the slop, while still allowing it to spin freely.

Cheers,
Gable

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Thanks for checking it out. Since I’m using an AR45P rear from a 10.3, it’s virtually the same width as the AR44 variant front axle so I didn’t need to do anything special with the hubs. I’m not too sure which hub would get you closest as I haven’t done the math on the difference in widths from the Capra to the AR44s.

Nice, glad it worked out for you. Thanks for following up "thumbsup"

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Ok gotcha. I assumed the Capra and 10.3 axles were the same width. I haven't done much research on them. Thanks for the reply.

Re: Topher Builds a Sherpa - Rear Portal Class 2 comp truck
 

Hey Man what Links are you using on the chassis the one that looks black aluminum in the rear? 67mm or 70mm? thanks just starting my first comp build and Gabe from Gspeed has been helping me out but could use some guidance may do four wheel steering also???? Ill send you some organic Honey Form TN for help on this build!!! ,,,,, Buzzzzz....... Buzzzzz.......
