I absolutely love my 14" collapsible dob, and find I get a fair bit of use out of it.  But, of course, it's a beast to move.  I've been considering adding wheelbarrow handles to it, as I've seen in other places -- but somewhere, possibly even on this site, I saw a big caution about drilling holes in this dob's base, as it's particle board.

 

Moreover, there was concern about whether the particle board itself would even stand the force exerted by the handles while in motion.

 

Can anyone comment on these issues?  While I accept that I could get a flatbed dolly to transport the scope, that still presents the challenge of lifting the dob up onto the dolly platform, something that, while not horrible, would get old.  There's also the issue of dolly wheels not typically being suited to grassy or uneven terrain.

I put wheelbarrow wheels on my Meade Lightbridge, which is also made from particle board and I just drilled some holes in it and bolted the handles to it... That was a couple years ago. No issues so far, but it also stays inside, in an unheated room, when not in use. 

 

Here's the latest version of my modded Lightbridge:

The wheels are solid, puncture-proof tyres. The round rocker box bottom has been replaced with a square one and the ground board with a round one, not larger than the rocker box minor axis. This saves A TON of weight and makes the rocker box assembly MUCH more compact. It is slightly less stable, but nothing dramatic. I plan on either do a complete rebuild of the scope or just get a more modern dob outright.

 

 

Clear skies!

Thanks Thomas!  Do you remove the handles when you observe, or do you just step carefully around them? (Looks like there *might* be wingnuts holding the handles on, but I can't be sure...)

With just slightly bigger wood handles that were notched on top instead of bored through, you could easily set it down and then move the handles out of the way, if the tires had a shared rod/bolt for an axle...also the bolts could then be made shorter so as to not be as likely to be "ankle biters"! Round them off so they won't bite you as bad... just be sure to keep it "pinched" between them while moving it or put some oversized washers on the ends of the bolts to keep them in place while using it. Gravity would hold it in place over most terrain or small steps. Great design Thomas! If I ever get me a big dob I'll remember this. Those yellow tires are cool too!

How do you prevent the tube part of the scope from tipping over when you move the telescope with wheelbarrow handles?
