I have the Bogart Tow bar. My nose gear is a Matco wheel with Matco axle.



When I put the tow bar on the axle bolt and nut, the tow bar slips off very easily, making turning and pushing almost impossible Is thee a way to lock the tow bar onto the axle?-sent from the microchip implanted in my forearm

You do not use the wheel axle bolt for the tow bar. You use the forward tow bar attach 

Bolts That hold the front of the wheel pant bracket.

Geoff answered the question but you might give this some thought as work 

on the brackets....



As I recall, the original design has the 'forward tow bar attach bolts' 

setup so they are recessed inside of the wheel pant for a nice 

streamlined appearance/performance.  I copied a number of other builders 

in  lengthening the bolts so that stainless cap head bolts sit external 

to the wheel pant.   There was a bit more to it but it's been awhile and 

I'm not looking at anything.  The mods were fully discussed and 

documented here on the forum.



As I go into 5 years of operation, the external tow points have worked 

great with the Bogert tow bar.  More importantly they have eased 

operations at visiting airports because the tow points are obvious, 

easily used by common commercial tow bars, and because of some 

protective washers they minimize damage to the wheel pant from line 

folks.  And it still looks pretty good though not all neat and recessed.



There may be other and better solutions out there now but that mod has 

been good to me and I recommend it.



The Bogie Bar has also be come my control lock - it can work without 

modification but the addition of some tabs  to lock into the rudder 

pedals makes it fool proof.

I lengthened my tow bar attach points by buying longer socket head cap screws and machining longer aluminum spacers.  The attach points are just flush almost with the fairings. They do not stick out and provide about 3/4" attach points for positive tow bar connections.

HI



A few years ago there was a bolt / helicoil / tap kit that was making its way from builder to builder.



The intent was to use heilcoils in the bolt holes as the raw aluminum would eventually give way. The bolts were longer so that the head protruded out of the pants. A large washer was placed under the head so the tow bar never was inside the wheel pant. This prevents wheel pant damage if the tow bar slips off. AT least only paint gets scratched and the F/G doesn't get This up.



Cheers

Thanks Les - it was long enough ago I forgot most of the details but 

that's what I did.  The heli-coil touch was good engineering.  Without 

it, I'm sure things would have stripped.



Extending to just below the surface is the showplane approach - very 

nice.  The extension with large washer approach is the 'ham handed tow 

bar handling' approach.  Both better than stock I'd guess.

Here is a photo of how I extended the tow pins and used chrome hex bolts.  I also used a helicoil for the attachment threads

I took the Bogart tow bar, cut off the female pickup ends, and welded on pin tabs that would go inside the allen bolts.  That way no other tow bar will work.  Disadvantage = no other tow bar will work.  Advantage = the holes required in the wheel pants are smaller, and no one else will try and use their tow bar to move my plane.  If I trust them to move it, I will leave mine with the plane.  6.5 years, 800 hours, no problem.
