When grubscrews or mounts fail, you can always use JB Weld 8265S Original Steel (or your local automotive parts store name-brand engine block repair two-part epoxy)
Of course that makes it permanent. And always mix very well, in correct proportions, and let it cure a few more days than it says you need to.
Yes, I ship from Norway so there will be import fees. Currently you can choose between NOK or USD on the site. Most of my customers are US based.
I was fed up with this exact issue with other mounts. This is actually the reason whooshboards exist. Thatās why I made sure not to have the same issues when designing my own mounts. Mine fit both caliber II and TB218 100%. No slipping of angle. Good ground clearance. 7075 t6 alu. Optional crossbars and idlers. I do not know any other mount with all these features.
@Von @BillGordon @gmurad @BleepBlopBloop @Jujo Help me out guys, maybe you have some insights to share about the mounts? 
Iāve actually only had good experiences with these mounts. I remember receiving them and thinking these are gonna be rock solid. And they were! I got the 80mm adjustable plates with hex clamps so I had a lot of angular options depending on clearance. I prefer the C-shape type of clamp but these split clamps were great.
My only issue was that they came with stainless steel and I donāt trust stainless steel unless theyāre butt plugs. Too low tensile strength. So I swapped them out for class 12.9. And oh! I generally hate branding and logos, but these were just so nicely made, I didnāt mind them eventually.
Iād say these are top 3 mounts for me personally. Just under Janux mounts but way better than those painted Psychotillers mounts for TKP or RKP
Sorry I keep editing and adding shit. Important note: Iāve never had to use a loctite for these mounts because theyre pretty solid. (not that you shouldnāt to be extra safe!)
I have some āb-stockā you can get discount on. Just PM me
I have a set of streetwing ones with belt covers you could have for shipping costs if that tickles your well oiled fancy.
Never used or mounted.
Iām sure I have a bunch of other brand ones too here somewhere that I didnāt use because I am a hoarder.
Ummā¦I could use a mount 
Thanks for the offer, but Iāve seen pictures of those mounts breaking where the motor attaches because of the metal being too thin. Whooshboards has sorted me out for the time being 
Are they still up for grabs or gone already? Late to game like always
Sorry a bit late to the party. Have been absent from this forum due to privacy issues that have surfaced.
Whoosh boards mount are still on my board and havenāt budged one bit. They are secure as a rock and I havenāt used loctite as the bolts have nylon lock on them. I have only used whoosh mounts and I canāt think of a reason for using anyone elseās. They are compact well designed and secure af.
In fact the maytech 6355 have taken a crap and the these still stay on rock solid.
