Hey- I got a set of holeshots from Jewkes and am having a little trouble getting the car line up. The car is an extended wheelbase railrider with the cog at about 7/8th inch. I'm using Jewkes grooved axles as well. The axles holes were drilled using the pro body tool and the car was cut from oak.
I'm shooting for about 1" of pull for about 4' of travel. The axles are canted about .001" cuz there is no way to adjust the wheels any other way. What Im getting is about 4" of pull, and when i try to straighten it out a little, the wheels seem to bind up and the car has difficulty rolling. The wheels seem to ride out towards the axle head fine, and it rolls fine, it just when I try to make it run a little straighter everything gets messed up and the wheels seem to go in all different directions! Im ready to save the wheels and axles and throw the car at my dog.....
Any ideas?
thanks-
Rick Miller

First thing about these wheels or any Thin Mod wheels...
Canting the wheels is not recommended... try and run then straight up as possible for better balance and stablility...
Also turn the front wheels inside out...
This will make your front end a little narrower than the back wheels you don't want your back wheels to tough the center guides.
Also make sure the gap between the wheel and body is only about 1/32th". this will help the thin wheels stay more stable when rolling forward. You don't want side to side movement.
When using the pro body tool to drill holes in the block its is hard to get front to back line up the same cause when you move the tool after drilling the first set of holes the tool is no longer in the same possition as it was first set up to. making next to impossible for perfact alignment.
Contact Jewkes Engineering for futher help on this subject.

Ok, thanks. I will try pulling the axles, pressing them back straight and starting over with straight axles.
Do you think it would be a stupid idea to buy a second pro body tool, then drill both front and rear axles at the same time?

Rather than buying a "pro-body" tool, I would suggest getting "The Block" from Jewkes Engineering, because it is designed to drill all 4 holes with one setting. It may be the next biggest reason for fast times due to ease of alignment issues. You have to try it to believe how it works!

How would one go about purchasing one of the "blocks"?
How much are they?
Always looking to try things to make my life easier.

To get "The Block" either PM or contact Glen (2fast4U). The block isn't cheap (I don't remember the cost) but is well worth it - especially if you help other kids to build cars. I run a cabinet shop and get a lot of father / son teams coming in for help with rough sizing and ideas.
